When the show does hit the air, it will be filled with yet another bunch of new faces, including Ciaran Hinds (“Political Animals”) playing Mance Rayder, the king beyond the wall, and Diana Rigg, who will play Marjorie Tyrell’s grandmother, Lady Olenna Tyrell.

“Diana Rigg, man. She’s a legend. And of course, she’s done many great things, but she [is] perhaps still best known for playing Emma Peel in the original ‘Avengers’ on British television, but was then syndicated in the United States,” George told AccessHollywood.com at Comic-Con 2012 in San Diego of Diana’s casting. “Fantastic show, brilliantly written, brilliantly acted and she was the hottest woman on television or like — in the world — and I was madly in love with her… like all the other boys of my generation.”
